Answer: x = {-2, 2}
<u>Step-by-step explanation:</u>
Tangent means it is touching. Find the intersection of the two equations.
Solve the linear equation for y, then set the two equations equal to each other.
To find the next point that is parallel to the linear equation and tangent to the curve, we need to use the linear equation with slope (m) = and unknown b.
Let's try b = 0, then the equation of the linear equation is:
Set the equations equal to each other and solve for x:
This works!!! If it didn't work, we would have tried other values for b until we arrived at a solution.
